Modernise the network

How software-defined networking and cloud-delivered security converge at distributed edges, so access policy follows the user, the device and the data.

How an application-aware overlay picks a path across mixed transport, why that is a routing decision rather than a security one, and what it leaves for something else to do.

How brokered, application-specific access replaces network-level connectivity, and what an over-broad application definition gives back.

SSE is the security half of SASE. Where the boundary falls decides whether branch and wide-area connectivity is part of the purchase or still your problem.
